LIFE OF CHAPTER XIL OF HXJMBOLBT'S LIFE—ILLUSTRATIONS OE TRAVEL AJO> OF JSTATUBE. THB life of Alexander von BCunxboldt is so fertile in objective and subjective events, that it was impossible to represent the various scenes of his adventures, scientific and social, in former chapters. We often hurried over events, views, and landscapes, in order not to fall from the field of the biographer into that -of the writer of travel; but we often wished to tarry longer, and give the dangers and impressions of new, bold discoveries, or try the effect of many a beauti- ful natural scene upon the mind of our reader. As we wish, however, to satisfy the readers of this bio- graphy in this respect also, and bring Humboldt be- fore the people in the various circumstances of his glorious activity, and in order once more to follow him in his thoughtful contemplation, clear explana- tion, and instructive tuition of nature, we have gleaned some stray sheaves on the paths traversed in the previous chapters. We append, therefore, some scenes of travel, natural phenomena, and views, extracted from Humboldt*s writings, as a gallery of sketches which will fill up the crude outline, and the gaps in our portrait of Huinboldt.
